mate-screenshot saves extra pixels outside of window when grabbing current window

[Michael Olberg]

The title says it all, when taking a screenshot and asking only for the current window, I am expecting the resulting image to stop at the window boundary. In 20.04 I am getting an extra 10 pixels on all sides from the background screen, see attached example.
